Abstract
A document scanning apparatus includes an automatic document feeder having at least a pick-up section for picking up documents to be scanned and a feed-out section which ejects the scanned document. A sensor in the pick-up section detects the length of the document to be scanned. A stamp located at the feed-out section marks the scanned sheets with a stamp and is controlled by a controller which controls the stamp position based on the length information obtained by the sensor in the pick-up section.
Claims22
A document scanning apparatus, comprising:
- an automatic document feeder having a pick-up section including a first document reversal section which reverses an orientation of a sheet picked up from said pick-up section from facing upwardly to facing downwardly, and a document eject section including a second document reversal section which reverses an orientation of the sheet from facing downwardly to facing upwardly;
- a sensor in said pick-up section for detecting a length of a document to be scanned;
- a scanning mechanism disposed at a region under the automatic document feeder between the pick-up section and the document eject section;
- a stamp located in said document eject section for stamping a scanned document;
- and
- a controller for controlling a stamping position on said scanned document using said detected length of said document.

A method of scanning and stamping a sheet, comprising the steps of:
- feeding a sheet having data thereon facing upwardly from a feed tray into a document feed section;
- determining a length of said sheet using a sensor in said feed section, when said sheet is in the document feed section;
- reversing a position of said sheet to have the data thereon face downwardly while advancing said sheet through the feed section to a scanning portion;
- scanning said sheet at the scanning position;
- determining a distance between the scanning position and the stamped;
- determining an advancing distance the sheet is to be moved from the scanning position to reach a sheet stamping position using the determined length of the sheet and the determined distance between the scanning position and the stamper;
- advancing said sheet said determined advancing distance from the scanning position to the sheet stamping position;
- and
- stamping said sheet while said sheet is at the sheet stamping position.
6 more elements
An apparatus for scanning and stamping a sheet, comprising:
- a feed tray for holding a sheet having data thereon facing upwardly;
- a document feed section disposed next to the feed tray including a document reversal roller which reverses an orientation of the sheet;
- a sensor disposed within the document feed section;
- a scanner located at a scanning section;
- a stamper located at a sheet stamping position;
- and
- a control means for:
- commanding a feeding of the sheet from the feed tray into the document feed section;
- commanding an advancing of said sheet through the feed section to a scanning position disposed next to the scanning section so that the data thereon faces downwardly after having the orientation thereof reversed by the reversal roller;
- determining a length of said sheet using the sensor in said feed section, when said sheet is in the document feed section;
- determining a distance between the scanning position and the stamper;
- commanding a scanning of said sheet at the scanning position;
- determining an advancing distance the sheet is to be moved from the scanning position to reach the sheet stamping position using the determined length of the sheet and the determined distance between the scanning position and the stamper;
- commanding an advancing of said sheet said determined advancing distance from the scanning position to the sheet stamping position;
- and
- commanding a stamping of said sheet by said stamper while said sheet is at the sheet stamping position.
